WILLIAM W. ARMINGTON, OF LOWELL, MASSACHUSETTS, ASSIGNOR TO GEO. E. MITCHELL, OF SAME PLACE.

ICE-CRUSHEFL` Specification forming part of Letters Patent No. 50,198, dated September 26, 1865.

To all whom tt may concern:

`'Be it known that I, WILLIAM W. ARI/LING- TON, of Lowell, in the county of Middlesex, and State of Massachusetts, have invented a new anduseful Improvementin Machines for Crushing Ice,for any purpose where small fragments are desired, and I do hereby declare that the followingisa full and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification, of which- Figure l is a longitudinal vertical section of my improvement, the plane of the section passing through the center. Fig. 2 is a detached plan or top view of the ice-box; also the sides and thelower part of the back. Fig. 3 is a bottom view ofthe crusher-head.

Similar letters of reference indicate corresponding parts in the three figures.

The nature of my invention consists in the employment of a disk or crusher-head having sharp prongs or teeth projecting from the under side of it, when the said teeth are made to act upon the substance of the ice against a plain surface upon which the ice rests, so as to allow each fragment to move as soon as it is separated from the piece of ice being` crushed, and the plain-surfaced bottom is made to rock or tip on pins or other supports, so as to tip forward and allow the fragments to be easily removed. A shaft or shank is secured to the top side of the Crusher-head to guide it up or down in grooves or guideways made to receive the said shaft or shank.

In the drawings A is the plain-surfaced bottom, supported at the back by a ledge, d, and at the sides by pins b I) passing through the sides 7c 7c of the machine, which sides are firmly united with the back F.

Arms I and J extend forward from the back F, and suitable guideways are formed in the said arms in which the shaft or shank D moves up or down. Caps mm, secured to the ends of the arms I and J by screws n n, hold the shaft in its place.

The Crusher-head B is cast onto the shaft D or otherwise rmly secured thereto, and several sharp prongs or teeth G project downward from the bottom surface ofthe same. Sides o o o rise from the extremities of the bottom A, forming a box for the reception of the ice which is to be crushed; also preventing leakage between the extremities of the bottom A and the sides K K of the machine. The spout or nose L provides for the easy removal ofthe crushed fragments or of water in case a portion ofthe ice should mclt.

The lever E is hinged at the top ofthe back F by the pin g. Downward motion is given to the shaft D and Crusher-head B by the lever E acting upon the pin h in the circular slotj'. The spring H is secured at the top b v the hook e, attached to the arm J, and at the bottom by the screw P in the shaft D, and serves to produce the upward motion of the Crusher-head B.

The object of my invention will be readily seen. When smallfragments of ice aredesired for use, a piece of ice of suflicient sizeis placed upon the plain-surfaced bottom A in the icebox.

Downward motion is given to the lever E by the hand ofthe operator or otherwise, forcing several of the teeth O into the piece of ice, crushing and splitting it into small fragments,

said fragments sliding off from each other on the plain-surfaced bottom A. The spring H raises the Crusher-head, when the ice-box is rocked or tipped forward, and the fragments removed through the spout L.

I do not confine myself to the precise form or length of the teeth or prongs on the crusher-head B,as thatwill of necessity be governed by the fineness of fragments and the ainoumt of ice to be crushed. v

The combination of the crusher B, the pivoted box A, the shaft D, lever E, and spring H, operating substantially as and for the purpose specified.

NVILLIAM W. ARMINGTON.
